The present invention discloses a Beidou navigation and location optimization method based on a mobile terminal. The method comprises: obtaining BeiDou satellite location information and signal intensity of the BeiDou satellite, and performing marking on a navigation map module; when the BeiDou satellite is employed for location, if the signal intensity of the BeiDou satellite is higher than the highest signal intensity threshold value, continuously using a BeiDou satellite location mode for location; and when the signal intensity of the BeiDou satellite is lower than the lowest signal intensity threshold value, starting an interference processing unit to perform filtering amplification of the obtained location information. The BeiDou navigation and location optimization method based on the mobile terminal can perform detection and optimization of the signal intensity of the BeiDou satellite when a single mode generates the phenomenon of a signal blind area or signal loss and can perform intelligent switching according to different signal intensities so as to avoid the problems that the location is lost and the location cannot be performed after a signal intensity blind area is entered in the location process through adoption of a traditional BeiDou satellite.
Description
technical field [0001] The invention relates to the technical field of Beidou positioning, in particular to a method for optimizing Beidou navigation and positioning based on a mobile terminal. Background technique [0002] The Beidou Satellite Navigation System (referred to as the Beidou System, the English name is BeiDou Navigation Satellite System, abbreviated as BDS), generally refers to China's second-generation satellite navigation system, referred to as BDS in English, it used to be called COMPASS, also known as Beidou No. 2, It is an independently developed and independently operated global satellite navigation system that is compatible with other satellite navigation systems in the world. It is also one of the most critical national infrastructures in our country. [0003] At present, the Beidou system has been applied in more and more fields, and has formed a certain market scale in various aspects such as positioning, navigation, timing, and communication. From t...
